[suse-oracle] ocfs2 problem after sles 10 SP2 upgrade

Hello to everyone !

We had an sles 10 Sp1 , oracle rac 10.2.0.4,  ocfs  combination wich worked
fine for about an year !
After we've done some testing we decided to upgrade to sles 10  Sp2 !
After upgrade we've notice 3 problems so far :

   1. rman ( oracle tool for backup) doesn't work anymore from the local fs
:

   2. in /var/log/messages we have :

The only thing we found about that is a novell document, id = 7000562 wich
resolution is "please open a service request ... ".


 3. in oracle's alert.log we found that arch process can't write :



ARC1: Encountered disk I/O error 19502
Mon Apr 13 13:02:36 2009
ARC1: Closing local archive destination LOG_ARCHIVE_DEST_1:

Mon Apr 13 13:02:36 2009
Errors in file /oracle/PRD/saptrace/background/prd001_arc1_9381.trc:

ORA-27061: waiting for async I/Os failed
Linux-x86_64 Error: 5: Input/output error
Additional information: -1
Additional information: 1048576


This one we solved by disabling the disk_asynch_io and filesystemio_options
! The efect is that performance is affected (but at least the arch
process is ok now );


Any help is appreciated !
